Unformatted text preview: Numbers of orbitals Numbers of orbitals W There are 2l+1 orbitals in each subshell W There are n 2 orbitals in each shell W There can be 2n 2 electrons in each level Counting Counting Orbitals Orbitals W n = 1, 1; n = 2, 4 (2 2 ); n = 3, 9 (3 2 ) W n 2 orbitals at each level, and because each orbital can hold 2 electons 2n 2 electrons at each level Notation Notation W n=4, l =2 4d W number of electrons indicated with superscript W 2p 2 means the 2p subshell contains 2 electrons (can hold a maximum of 6) Orbital energies in the multi Orbital energies in the multi-- electron atom electron atom W Attraction between electrons and nucleus is coulombic F=q 1 q 2 /r 12 electrons repel each other W Shapes of orbitals have different average distances from the nucleus s closer than p closer than d closer than f closer electrons shield electrons that are farther out from the nuclear charge Chapter 8 Chapter 8 Electron Configurations, Atomic Properties, and the Periodic Table Orbital energies in the multi...
